IMPORTANT! Changed configuration to use Apache rewrite rules. Add this at the end of your apache2.conf or httpd.conf:

# Symfony
Alias /eva  "/var/www/MeloLabEva/web/"
<Directory "/var/www/MeloLabEva/web/">
    Options Indexes FollowSymLinks Includes ExecCGI
    AllowOverride All
    Require all granted
</Directory>
